Welcome to EarthTec QZ

EarthTec QZ (QZ) is an EPA-registered molluscicide for prevention and control of quagga and zebra mussels. QZ’s unique liquid formulation is proven effective at killing adult mussels and preventing settlement and infestation by larval-stage veligers.  (See the Technical section for independent studies)

QZ is NSF-certified to ANSI Standard 60 for drinking water, making it one of the most practical approaches available at controlling the spread and infestation of this devastating species.  EarthTec QZ can be applied in lakes, reservoirs and pipelines leading to water treatment facilities.  It is a product that is rapidly dispersing and immediately bioavailable.  The zebra mussels do not detect QZ as a threat and readily ingest it. Studies generally confirm complete mortality within a 48-96 hr period of time. It has also shown to be effective at concentrations that are non-toxic for most fish and other non-target organisms. 

EarthTec QZ is the cost-effective and proven solution of choice at municipalities across the U.S. Please contact us to discuss how we can help address your infestation too.
